POLYMER LAYER COMPOSITE WITH FERROELECTRET PROPERTIES AND METHOD FOR PRODUCING SAID COMPOSITE

摘要

The present invention relates to a polymer layer structure with ferroelectret properties, comprising a continuous first polymer layer (1) and a continuous second polymer layer (2), wherein the first and second polymer layers (1, 2) are connected to one another by means of connecting sections (3) arranged between the continuous polymer layers (1, 2) so as to form cavities (4). According to the invention, the polymer layer structure is in the form of an integral extruded component.
